Ferro gem® is a 6% straight ferrous sulphate which is used to green & toughen up grass. Apply by knapsack or boom sprayer to ensure there is good coverage of the moss. Use 600-800L of water per hectare to help improve coverage of thicker swards of grass.

Ferro gem® can be used all year round including during colder spells of weather, where it will help strengthen the plant against frost and disease. Iron is absorbed by the leaf giving rapid results and has been known to blacken moss within hours. This product is ideal for treating large areas such as horse paddocks & amenity areas. While ferrous sulphate is not harmful or hazardous, we would recommend keeping livestock off the treated area for 24-48 hours. For an all-in-one treatment, look at Green Force Weed, Feed & Moss Killer

If using Ferro gem® on thick infestations of moss in grass, consider using Evoque Enhancerwhich will help improve penetration and results by up to 20%

**Due to recent changes in the law, products which contain ferrous sulphate can no longer be claimed to have control against moss. This is because any product which 'controls' moss is now classed as a herbicide, and this requires the product to have an expensive and complex approval. Due to this, we are unable to claim that this product will control moss; In spite of the fact that the product formulation has not changed since when it was used to control moss with very good results**
